Mrs. Nelson gave her students a task: Start with the expression 2x^4.

Add, subtract, multiply, divide, or use exponents to make a new expression that is equivalent to 16x^10.

The answers of several students are shown below. For each student, determine if they are right or wrong. Then explain why using your exponent rules.​

Step-by-step explanation:

Step-by-step explanation:

the mean is simply

8+9+3+9+3+8+4+4=48

48/8=6

mean= 6

the median is simply

3,3,4,4,8,8,9,9

4+8=12÷2=6

median=6

the mode is simply(I'm not sure of this answer)

3,4,8,9

the range is

9-3= 6

Answer:

The table in the exercise can be completed with the next results:

Step-by-step explanation:

As in the exercise Janice is 7 years older than Tam, to obtain the result in the table, you must add 7 to each age in the column x, with this we can make the next formula:

Remember that x is Tam's age, and y is Janice's age, so, you must replace the x variable in each case to obtain the result to y:

When x is 2:

When x is 4:

When x is 6:

When x is 8:

At last, to obtain the graph you can use the formula made: y = x + 7, and you'll obtain a graph like the attached picture, where each time x obtain a unit, the y variable obtain a unit too maintaining the diference of 7.

Answer:

3 goals

Step-by-step explanation:

Lets say the 12 goals is 100%

Luke scored 25% of those goals

So to find 25 percent of 12 multiply 12 by the percent 25

25 times 12 is 300

divided by 100 is 3

Luke scored 3 goals

Tell me if this is wrong if not

Answer:

the last one

Step-by-step explanation:

the 100 dollars is an initial fee so it won't be multiplied at all. the 25 is daily so you would multiply that by each day which is d. you would add the 100 dollars because it wants to know the total price in the end. I hope this helps and I am truly sorry if it is not right.

Answer:

C. 52

Step-by-step explanation:

If this is a parallelogram then sides PS and QR must have the same length. If PS is 13 then 1/4y must equal 13. 1/4 of 52 is 13 meaning y must equal 52.

Answer:

52 is right

Step-by-step explanation:

Answer:

14.1 =x

Step-by-step explanation:

Since this is right triangle, we can use trig functions

sin theta = opp/ hypotenuse

sin 42 = x /21

21 sin 42 = x

14.05174273 =x

Rounding to the nearest tenth

14.1 =x

Answer:

x = 14.1 (Rounded to the nearest tenths)

Step-by-step explanation:

Since the opposite side of the angle given needs to be found out and hypotenuse, Sin ratio would be used;

Sin(42) = [tex]\frac{x}{21}[/tex]

=> Now multiply 21 on both sides of =, in order to isolate x;

Sin(42) * 21 = x

14.1 = x

Hope this helps!

Answer:

Lose 2oz of water in 1st minute and loses 2oz of water in 2nd minute.  this is false because this will not equal 0, it will equal -4oz because it is losing a total of 4oz in 2 minutes. So the answer is FALSE

Answer:

[tex]c=10x^2+22x-16\\A=6x^4+28x^3+14x^2-48x[/tex]

Step-by-step explanation:

Given

Length is [tex]l=3x^2+5x-8[/tex]

Width is [tex]w=2x^2+6x[/tex]

Perimeter of the rectangle is the sum of the sides

[tex]\Rightarrow c=2(3x^2+5x-8+2x^2+6x)\\\Rightarrow c=2(5x^2+11x-8)\\\Rightarrow c=10x^2+22x-16[/tex]

Area is given by

[tex]\Rightarrow A=(3x^2+5x-8)(2x^2+6x)\\\Rightarrow A=6x^4+18x^3+10x^3+30x^2-16x^2-48x\\\Rightarrow A=6x^4+28x^3+14x^2-48x[/tex]

Answer:

Below in bold.

Step-by-step explanation:

When x = 4 the denominator = 0 so the vertical asymptote is x = 4.

When x approaches negative and positive infinity  f(x) approaches zero  so the horizotal asymptote is y = 0 ( the x-axis).

Answer:

5 days

Step-by-step explanation:

dogs, combined, eat 80 ounches of food daily

there are 16 ounces in one pound so there are 25x16, or 400 ounces, in a 25-pound bag

400/80 = 5

25-pound bag would last 5 days

One bag of dog food volunteered by Amelia, Which have quantity of 25 pounds  will last for 5 days.

What is ratio?

Ratio is mathematical term, which we use for comparing two or more terms. basically it indicates that how much big or small is number in compared to another.

Given that,

Every day, Amelia puts out 10 ounces of food for each of the 8 dogs.

Dog food comes in 25-pound bags.

And it is know that,

1 pound = 16 ounce;

so by that way it can state that,

Dog food for 25-pound bag will be equal to;

25*16

400 ounce.

Everyday requirement of dog food is 8*10 = 80 ounce/day

Number of days food will  last= Available quantity/Everyday requirement

Number of days food will  last= 400/80

Number of days food will  last= 5 days

Hence, One bag of food will be enough for 5 days.

Answer:

48

Step-by-step explanation: because 4/6 = a .66666666666667. and that times 72 is 48

Answer:

58 :)

Step-by-step explanation:

the two angles make up a right angle with is 90 degrees so 90 minus 32 is 58.

Answer:

SO we can see that x is part of a 90 degree angle

whats also included in the 90 degree angle alongside x is 32 so the equation will look like this

x+32=90

just solve from here

90-32=58 = x

hope that answers your question :)

Answer:

Least speed = 33.66 km/h

Step-by-step explanation:

The least distance is 119.5 km, and the most time it took was 3.55 hours.

Therefore the least speed = least distance/most time

= 119.5/3.55 km/h

= 33.66 km/h

Hello! answer: 276

I dont know for sure though cause the model looks different from what I've seen before so answer at your own risk but I'm pretty sure this is right Hope that helps!

Ok so what I did was base × height for the rectangles because thats the formula for those those I got 70 for both the left and right the left isn't showing but I'm assuming its there its 70 for both because 14 × 5 = 70 then for the bottom is 112 because 14 × 8 = 112 then the two triangles are 12 each because 8 × 3 = 24 then divide by 2 because thats what you do for triangles then I just add all these numbers up so... 70 + 70 + 112 + 12 + 12 = 276
